Hardy avocados

Q: I intend to gift three avocados, at least one type A and one type B, to a friend who lives in an area where the temperature never goes below 25F. The idea is to give them a ripening season as long as possible. Which combinations do you suggest, and which are the A and B?

A: When talking about "A" type and "B" type in Avocados, it is referring to the flowers. An avocado will produce both male and female flowers on the same plant. "A" type means that the flowers are female in the morning and male at afternoon. "B" type means that the flowers are male in the morning and female in the afternoon. If you plant to start a commercial growth, then it's important to create a proper mix of both types. However, in hot and humid climate a single tree produces flowers of both types, so it is not necessary to have both A- and B- types planted together in backyard. Even a single tree produces enough fruits for home gardener.

It is also important to know that while there are more cold hardy avocados, it refers to a full grown established tree. They will still need protection from the cold until they are bigger and more established. One can not expect a small tree, which was planted in June, to survive the first winter. It'll take few years until the tree is "harden" enough.

Wurtz Avocado: Fruits from May to Sept. Dwarf hybrid. It is very compact and slow growing, reaching only about 8-12 feet at maturity. Distinctive weeping growth habit. Suited for planters, containers, patios, greenhouse use. Great for dooryard or container growing. The tree can handle temperatures to 25(F) degrees. Production is good and it is a consistent bearer.

Day Avocado: Fruits July to Sept. Day avocado is green, smooth skin and is shaped like a club. The fruit is of very good quality and has a nice buttery consistency. The slender tree is relatively cold tolerant and produces July through September.

Fuerte Avocado: Fruits Nov to June. Relatively cold hardy variety. Green fruit, elongated,flavor excellent, buttery. Vigorous compact tree with decidedly alternate year bearing habit. Ripens November to June.

These three will provide you with fruit ripening during the whole warm season. For the most cold hardy avocado varieties, see this info sheet.

Adenium rainbow: 9 dark tones that don’t look real 🌈

Some adeniums are bright and cheerful.
And some look like they came from another planet.
This set leans into those deep, off-purple, almost unreal shades. Every one is different, but they all share that exotic, hard-to-describe look.


💡 Container tip



Adeniums do best in shallow containers, especially unglazed clay pots.
Clay helps in a few ways:
- it dries faster than plastic
- provides better air flow to roots
- keeps the plant stable as the caudex gets heavy

Avoid oversized pots. Keep it just slightly larger than the root ball.

Secret of a Big Caudex:
When repotting, raise the caudex a little each time.
That’s the simple trick to developing that thick, exposed base everyone loves.

🌸 Today's featured adeniums

  •  ✦ Blue Diamond: Cool-toned, almost metallic shades - very unusual in color.
  •  ✦ Musk: Modern-looking bloom with a bold, unconventional feel.
  •  ✦ Hong Hern: Elegant form with deep tones and a refined structure.
  •  ✦ Mad Lady: Twisted, expressive petals - looks a bit wild and unpredictable.
  •  ✦ Moung VN: Soft purple shades with a smooth, balanced look.
  •  ✦ Petch Pratum: Rich color with a jewel-like quality - name reflects that.
  •  ✦ Maneenate: Layered bloom with a more intricate, detailed structure.
  •  ✦ Ramruay: Associated with wealth and prosperity - strong presence.
  •  ✦ Swan and Dragon: Myth-inspired look with a dramatic, flowing form.

This kind of set is where collecting gets interesting - not just colors, but personality in each plant.
And once you start noticing these darker tones - you start seeing them differently everywhere.

🍭 From Vine to Bean: A Practical Guide

Vanilla  planifolia  vine  climbing  a  support,  close-up  of  vanilla  flower,
    and  cured  vanilla  beans

Vanilla planifolia Vine, Flower, and Cured Vanilla Beans

How to Grow Vanilla: quick how-to

Vanilla is not complicated, but it does have preferences. Start with a pot and regular, well-draining mix. It does not need anything exotic. Give it:

  • Bright, indirect light
  • Warm temperatures
  • Good humidity
  • Air movement

Most importantly, give it something solid to climb. A wooden trellis, a log, or a burlap-covered board works well. The surface should be porous so the aerial roots can grip.

As it grows, guide the vine gently. You can prune it to control size. Vanilla is slow to mature. That is normal.

The Bloom Secret

Vanilla does not bloom just because it looks healthy. It blooms when it feels secure.

This is a climbing orchid. It must attach firmly to a solid, porous support such as a wood log, trellis, or burlap-covered board. When the aerial roots grip and the plant reaches maturity, flowering becomes possible.

Once the flowers appear, they usually need to be hand pollinated to produce pods. Each flower stays open for only a short time, so timing matters.

How to pollinate vanilla: In this video, we show you exactly how to pollinate vanilla step by step

❓Vanilla care: quick FAQ

  • Does Vanilla planifolia really produce vanilla beans?
    Yes. Vanilla planifolia is the commercial source of vanilla. After flowering, it can form long green pods (vanilla beans). The aroma develops later during curing.
  • What is the secret to getting vanilla to bloom?
    Let it climb. Vanilla is a climbing orchid and usually will not bloom until its aerial roots attach firmly to a solid, porous support like a wood log, trellis, or burlap-covered board.
  • Do I need to pollinate vanilla flowers?
    Yes. In most home growing conditions, vanilla flowers must be hand pollinated to produce pods. Each flower is open for only a short time, so timing matters.
  • Can I grow vanilla indoors?
    Yes, if you can provide bright, indirect light, warmth, humidity, and a support to climb. A sunny room with filtered light and a trellis or log can work well.
  • What should I use for support?
    Use a sturdy trellis, a wood log, or a burlap-covered board. The key is a porous surface that aerial roots can grip. Avoid chemically treated wood. Check out this very unusual way to grow Vanilla Orchid over a wall.
  • What potting mix should I use for Vanilla plant?
    Start in a pot with a regular, well-draining potting mix such as Sunshine Abundance. As the plant matures, it relies more on its support and aerial roots than the soil.
  • What fertilizer should I use?
    Sunshine Boosters Orchidasm is formulated specifically for orchids and will work perfecty for Vanilla orchid as well.
  • How big will it get?
    As big as you let it. Train it and prune it. Vanilla grows according to the structure and space you provide.
  • How long until it flowers?
    Typically a few years. Vanilla is a long-term project, but it is very rewarding once established.

Vanilla dilloniana in Bloom - Rare Florida Native Orchid

We also offer Vanilla dilloniana, a rare Florida native species with distinctive flowers.

One remarkable specimen of this species, grown by our friend Robert Riefer, became so vigorous over many years that it outgrew a 100 gallon container and was eventually moved into a 250 gallon pool on wheels.

The plants we offer are propagated from that very specimen:

That kind of growth reflects deliberate cultivation and ideal conditions - not something that happens unintentionally.

Vanilla grows according to the space and structure you provide.

For gardeners focused on producing real vanilla beans for the kitchen, Vanilla planifolia remains the right place to start.
