Description
Echinocereus enneacanthusSN|7930]]SN|7930]] is a caespitose cactus forming dense or lax clumps either loose decumbent, or erect with 20-100(-500) branches, usually branching before flowering. There appears to be quite a variation in spination, at least in number and length of spines. Two subspecies are recognized, the nominate form and subsp. brevispinus.
Blooming Season
It flowers in early spring (April through June in habitat) during mid-morning. Flowers close at night and reopen for 2-4 days. The fruits ripen in late summer.
Ribs
7-12 with uninterrupted but prominent warty crests.
Stem
Cylindrical, the longest sometimes prostrate, 5-14 cm diameter up to over 100 cm long (but usually much shorter). The stems of this species are soft or flaccid, pale to bright green and often remain wrinkled.
Radial Spines
5-9 per areole, 25-45 mm long, straight or slightly curved, needle-like, more or less flattened, bulbous at the base, brownish, often tipped or banded with darker brown.
Fruits
Round to ovoid pale yellow-green or dull reddish, , maturing to bright red, 20-30 mm, pulp white or pale pink. The fruit is edible. After the spines are removed from the green-brown flesh of the fruit, it can be eaten and tastes similar to strawberry, hence the name strawberry cactus.
Areoles
Circular 18-52 mm apart.
