(with a range from Baja California and Arizona north to Washington)[

Cultivation Details

Asclepias fascicularis is a plant of mainly Mediterranean climates with hot summers and cool or even cold winters and most precipitation falling in the cooler months. Outside of this type of climate, the plant will require a well-drained soil and hot summers, with some protection in cold winters, if it is to thive. This protection can often be applied as a mulch, though it would need to be removed before new growth begins in the spring otherwise slug damage is very likely to occur[

]. As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in the greenhouse for their first winter. Plant out when they are in active growth in late spring or early summer and give them some protection from slugs until they are growing away strongly.
Division in spring. With great care since the plant resents root disturbance. Pot the divisions up and place them in a lightly shaded position in the greenhouse until they are growing away strongly, then plant them out in the summer, giving them some protection from slugs until they are established..
Basal cuttings in late spring. Use shoots about 10cm long with as much of their white underground stem as possible. Pot them up individually and place them in a lightly shaded position in a greenhouse until they are rooting and growing actively. If the plants grow sufficiently, they can be put into their permanent positions in the summer, otherwise keep them in the greenhouse until the following spring and when they are in active growth plant them out into their permanent positions. Give them some protection from slugs until they are established.
