Caricature Plant


Graptophyllum pictum
A medium-size tropical shrub, reaching up to 8 x 4 feet, that is also grown as a summer annual ( up to 4 feet ) in cooler climates. It is great for use in planters in temperate climates.
The leathery leaves are up to 7 inches in length. The attractive multi-color foliage is the main reason this plant is grown.
Hardy zones 10 to 12 ( tolerating as low as 25 F though defoliating around 35 F ), thriving in sun or shade on just about any well drained soil that is consistently moist during summer. It is very heat tolerant but generally not drought tolerant except for very well established plants. They can be cut back hard if needed. It is fast and easy to propagated from softwood cuttings placed in water.

Cape Marigold

Osteospermum
Also called Dimorphoteca, these are not the true Marigold ( Tagetes ) though are distant relatives. They are used for edging, massing and planters. The very showy flowers have additional value in attracting butterflies.
Most species require full sun and are hardy zones 8 to 10. They thrive on well drained soils and are very drought and salt tolerant. Insects and diseases do not often attack these plants. Propagation is easy from seed sown after threat of frost has passed or cuttings taken during summer. The seeds should be sown on surface or covered very lightly and kept moist until germinating. Young plants should be pinched to encourage dense habit.
A highly recommended external site on these great plants is

They are easily transplanted from containerized plants. Pruning is generally not needed, however tip pruning after flowering and during early summer will encourage denser habit. Propagation is easy from cuttings.
