Armchair botanizing for Extreme Milkweeds (Asclepias)
Love them or hate them, you cannot deny the beauty of intricately crafted milkweed blooms, often deliciously perfumed and beloved by butterflies. Some Asclepias are well known invasive weeds, many are course stalwart plants more suited to a wild prairie garden, and relatively few may gain admittance to a rock garden. The North American west holds a number of fascinating dwarf Asclepias species, most will be challenging to cultivate.
