Hot novelty plant for hot Arizona

Q: What plants would you recommend for very hot and dry spot in front of my house that gets full sun all day long? I live in AZ, we recently had a couple good rains but this is going to be it for a long time. It gets so hot during the day that every plant I tried didn't make it. We have a few nice orange trees growing well but I would like to plant something compact, colorful and hopefully fragrant if there is such plant.

A: There is a perfect small size plant for you that is extremely fragrant and yet will be thriving in these conditions. It is the famous Jasmine sambac. It will appreciate dry air of Arizona and will bloom profusely for you in full sun or in partial shade. It doesn't mind heat at all.

For colorful accents, a proven winner is Crown of Thorns - Euphorbia millii. New giant size flower varieties were recently selected in Thailand, and we just received a great selection, look at the colors! These plants don't mind hot sunny location at all. The more sun, the better the bloom! Small plants need regular watering until establish, then once they start developing, they will require less water.

Giant Euphorbia flowers from Thailand are 4-5 times bigger than regular flower euphorbia. Diameter of the flower is around 2". Compare giant flower to normal size - picture on the right.

Growing Exotic Adeniums

Exotic varieties of Desert Roses. Adeniums have many spectacular hybrids. The basic culture is very similar to orchids. A small pot with excellent drainage is a must. Adeniums do not like both over-watering or drying-out. There is a secret how to create a large swollen caudex: raise the plant a bit every time you re-pot it, so that the upper part of roots will be a little exposed. The plant will form more roots that will go down.

To make your plant develop a large swollen base/trunk, you'll need a good quality fertilizer. Fertilizer requirement for swelling up trunks is also used to increase flowering. It shouldn't be too high in nitrogen, the middle number should be the highest (similar to 10-50-10). Never apply fertilizer directly on roots and do not liquid feed when a plant is thirsty: always water first slightly to avoid root burn and leaf drop. Do not wet leaves. Adeniums need lots of light for heavy flowering.

Most hybrids and species start blooming in the spring when the conditions are warm and days get longer, and continue blooming through the fall and winter in warmer climates. Adeniums like a neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot. Water plants preferably in the early morning, and allow them to drink up throughout the day. Watering can be done daily to every few days. Never allow your plants to sit in a saucer of water, but don't let them to dry out too often - this causes adeniums to go into early dormancy.

Planting instructions for bare-rooted succulent plants. Position the plant in a pot, size of root system. Use only well-drained soil with high content of Perlite and/or sand (cactus mix can be used), water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it.
