Safety & Hazards
This plant is best not used by pregnant women since it can reduce the supply of blood to the foetus[1].
Cultivation Details
Requires a deep moist well-drained light or medium lime-free loam in sun or semi-shade[2, 3, 4]. One report says that this species succeeds in alkaline soils[5] (a rather surprising comment considering the general needs of the genus - it is more likely that the plant can grow on limestone so long as the soil remains acid[PFAF]).Fairly shade tolerant[6] but plants produce less fruit when they are grown in the shade[4]. Prefers a cool damp position. Good fruit and seed crops occur every 1 - 5 years[7]. A very ornamental plant, there are a number of named varieties developed for their ornamental interest[4]. The form 'Massachusetts' is an especially prostrate, free-flowering and free-fruiting form[8]. 'Anchor Bay', 'Point Reyes' and 'Vulcan's Peak' have all been mentioned as good groundcover forms[4]. Most populations lack burls and are killed by fire; throughout the range in North America are occasional populations or individuals that have small, sometimes epicormic burls - these are able to resprout after fire[9]. This is one of the first plants to colonize bare and rocky ground and burnt over areas[10]. It is often an indicator of poor soils in the wild[11]. The plant is relatively insensitive to the effects of sulphur dioxide gas. Concentrations of heavy metals due to air pollution have been determined for fruit, stems, and leaves[7]. Plants resent root disturbance and should be placed in their final positions as soon as possible[3, 12]. Hybridizes with other members of this genus, especially Arctostaphylos columbiana (to produce Arctostaphylos x media), and with Arctostaphylos patula[7].
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[3, 4]. The seed will then usually germinate in 2 - 3 months at 15°c[12]. 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. The cuttings are very slow and can take a year to root[13, 14]. 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 of long branches in early spring[4, 15].
