Growth—

Arctostaphylos glauca grows in a mediterranean-type climate, with hot, dry summers and wet, mild winters[1]. Plants are tolerant of winter temperatures falling to around -5 to -10°c[2]. Requires a deep moist well-drained light or medium lime-free loam in sun or semi-shade[3, 4, 2] but plants produces less fruit when they are grown in the shade[2]. Prefers a warm sunny position[3, 5]. Found on dry soils in the wild, one report says that it succeeds in a hot dry position. Plants resent root disturbance and should be placed in their final positions as soon as possible[6]. Plants commence fruiting when around 20 years old, yields increasing with age to the extent that 90 year old plants yield around 15 times more fruit than 23 year old plants[1]. Plants can live for more than 100 years in the wild[1]. This species can hybridize in the wild with Arctostaphylos pungens and also with Arctostaphylos glandulosa[1].

Propagation

Seed - best sown in a greenhouse as soon as it is ripe. Arctostaphylos seeds, especially if not sown fresh, are generally stimulated into germinating by one of two methods. The most effective is fire passing quickly over seeds that are lying dormant in the soil - this breaks down their surface coat allowing them to imbibe moisture when it next rains and then germinate. Alternatively, stomach acids act upon the seed coat when the fruit is eaten by various animals - the seed frequently passes through the gut unharmed and is deposited in a convenient pile of nutrients when the animal defecates - the seed will often still benefit from a period of winter cold before germinating in the spring. Both of these methods can be somewhat reproduced by the gardener - the seed can be placed under some straw which is then set alight - both seeds and ashes should be sown. Alternatively, pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water will have somewhat the same effect as stomach acids. Follow this treatment with a cold stratification at 2 - 5°c for 2 months[4, 2]. The seed will then usually germinate in 2 - 3 months at 15°c[6]. As soon as they are large enough to handle, prick the seedlings out into individual pots, being very careful no to damage the roots, and grow them on in light shade in a greenhouse or cold frame for at least their first winter, Plant out in late spring or early summer. Cuttings of side shoots of the current season's growth, 5 - 8cm with a heel, late summer to early winter in a frame. Takes one year[7, 8]. Division in early spring. Take care because the plant resents root disturbance. Pot the divisions up and keep them in a lightly shaded position in a cold frame or greenhouse until they are growing away actively. Layering in spring[2]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Arctostaphylos+glauca>
