Growth—

Elaeagnus × maritima is native to the temperate regions of central and southern Japan hardiness zones 8 - 9.. It is unlikely to succeed outdoors in the colder regions of the temperate zone. Succeeds in most soils that are well-drained[1, 2]. Prefers a soil that is only moderately fertile, succeeding in poor soils and in dry soils[1, 2]. Succeeds in sun or shade[1, 2]. Very tolerant of maritime exposure[3]. hThis species is probably a naturally occurring hybrid, Elaeagnus glabra x Elaeagnus macrophylla[3]. This species is notably resistant to honey fungus[4, 2]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[2]. An excellent companion plant, when grown in orchards it can increase yields from the fruit trees by up to 10%.

Propagation

Seed - this is a hybrid and it will not breed true from seed. If this is not a problem, then the seed is best sown as soon as it is ripe in a cold frame[5]. It should germinate freely within 4 weeks, though it may take 18 months[PFAF]. Stored seed can be very slow to germinate, often taking more than 18 months. A warm stratification for 4 weeks followed by 12 weeks cold stratification can help[6]. The seed usually (eventually) germinates quite well[5]. Prick out the seedlings into individual pot as soon as they are large enough to handle and plant out when they are at least 15cm tall. Cuttings of half-ripe wood, 7 - 10cm with a heel, mid summer in a frame. Rather slow, but you usually get a good percentage rooting[5]. early summer is the best time to take cuttings[7]. Cuttings of mature wood of the current year's growth, 10 - 12cm with a heel, late autumn in a frame. Leave for 12 months. Fair to good percentage[5]. Layering in September/early autumn. Takes 12 months[5]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Elaeagnus+%C3%97%C2%A0maritima>
