Does xeriscapic mean boring and dry looking? Absolutely not! You'll never believe what beautiful blooms are available for the non-irrigated landscape. Come in and see.

A very pretty and very stinky plant.

Its looks make up for the smell though.

Euphorbia x martinii 'Ascot Rainbow' (Euphorbia characias x Euphorbia amygdaloides 'Rubra') was discovered by David Glenn in Australia.

I have found that even the hybrid euphorbias are good at keeping gophers and other plant/bulb-eating critters out of the garden beds. The euphorbia does need to be planted close to the plants/bulbs you want to protect.

I have had this plant for going on 9 years now. I still have the original plant that I have made starts from, so now have several colonies of this wonderful euphorbia. It puts on a wonderful show of color in the winter. Early spring I cut the old stalks back to the ground.

This is a gorgeous euphorbia all season long. My favorite is the winter color, because it provides such wonderful color when everything else is brown or just plain green.

I've read that it needs to be cut back in early spring, but that may be for well established plants. It's listed as full sun, but I think it'll be fine in part sun, like other similar euphorbias. I don't know whether deeper shade will affect the variegation.

This is a colorful and compact spreading Euphorbia. Both the flowers and the foliage are variegated. The flowers are a combination of cream and lime green; the foliage is cream with blue-green and the reverse is a pink or red. In the cooler months the foliage flushes even more red. Tolerant of heat and drought.

This hardy Euphorbia survived its first winter in great shape, but last winter was very mild, so I'm unsure of its continued hardiness here. I haven't watered or fertilized, and in full sun it's maintained a nice compact form with beautiful color. Last winter it was a nice dark red beacon although the form was open and unattractive up close. I pruned back to just a few inches in early spring and it apparently developed enough "old growth" because it bloomed very profusely. Update: Only about 1/4 of the plant put out new growth this year (2013).

I purchased two of these euphorbias in 2012. I was blown away by the way they looked the same that winter as they had in summer. I only cut back a few branches or part of branches late in spring 2013. They delighted me all through the growing season in 2013. Then came the winter. Deep snow and bitter cold temps. I lost both plants. I promptly bought two more in June 2014. I hope they survive this next winter, but if they don't, I will buy at least two more! Other than the problem with winter, these plants are drought tolerant and carefree in my zone 6 garden

This euphorbia has been thriving in a pot through a very cool summer. The colors in it have been very bright and colorful -- maybe deeper colors because of the cool, as some of the other Euphorbias do. Although its minimum hardiness is supposed to be zone 6, I will take cuttings, but I will also plant it to see whether it will survive the winter in zone 3 with heavy mulch.

I love this variegated plant for year-round color, especially during the dreary winter months. It looks good potted with white pansies and kale. I take cuttings during the warmer months to add plants to other planters and to share with friends, who always want a piece when they see it. Fortunately, they root very easily. Plants bloom in late summer and early fall, and the leaves turn a beautiful reddish color. I grow it in full sun.
