Angelonia salicariaefolia

Angelonia salicariaefolia, commonly known as Violet-flowered Angelonia, is a small shrub that grows between two and five feet tall. It is known for its fragrant, white to off-white blooms, which turn to blues, lavenders, and purples as they mature. It is a full sun to semi-shade loving plant, and needs regular or moderate water depending upon the climate. It can be grown year round in USDA Zones 9-11, with mature plants being cold hardy at least down to the 30s F for a short duration of time.

When it grows in pots, Angelonia needs to be taken care of in cold regions. To establish a healthy plant in the pot, plant it in a well-draining soil mix and place it in a sunny or a partially shaded spot. Make sure it is shielded from heavy winds too. Water it gently and regularly to keep the soil moist. Plants in brittle winter areas additionally need to be covered with a thick layer of organic mulch in late fall, to stay warm through the winter season. Use cold-frame protection when temperatures dip below t 30sF for extended periods.

Asarina sp.

Digitalis purpurea

It is a herbaceous biennial plant. Also freely self-seeds under favorable growing conditions, and, as with biennial hollyhocks, can establish colonies in the garden that will persist for years as if they were perennials.

The flowering stem develops in the second year, typically 1 to 2 m tall, sometimes larger. The flowers are arranged in a showy, terminal, elongated cluster, each tubular, pendent, purple (also pink, rose, yellow, or white in selected cultivars).

All parts of the plants, especially the leaves, are poisonous.

Globularia bisnagarica, Globularia punctata

The 2'' globes are typically bright blue, but some varieties exhibit lavender and purple flowers. The striking flowerheads of this plant are made up of many individual florets and remain attractive for several weeks.

These low-maintenance plants need little to no pruning and are considered deer resistant. They will also attract beneficial insects, such as bees, to your garden. Globularia bisnagarica is hardy in USDA Zones 5-10 and can be grown in a container in cooler climates. Plants grown in containers thrive when provided full sun, kept warm during winter months, and deadheaded regularly throughout the growing season. Container plants should also be kept moist but well drained, as they can suffer root rot with too much moisture.

Globularia x indubia

Globularia x indubia is the naturally occurring hybrid between G. sarcophylla and G. salicina. This is an unusual and beautiful small, dense shrub that grows to 2 feet tall and 5 feet wide with dark olive-green 2 inch long lance-shaped leaves.
