On a moist, well-drained soil, plant the among them is Nordmanns {AbiesNordmanniana), a tree reaching a height of150 feet and which is much in demand onaccount of its hardiness and beautiful foliage,dark green and shining above, silvery whiteon the lower surface. Abies concolor takesequal rank with this tree. It is recommendedespecially for the Eastern States, not only be-cause of its rapid growth and great hardinessbut also because it suffers less from heat anddrought than do the other firs. Other desirable firs are A. Cilicica and (of which the variety Apollinisis more hardy in the North), A. homolepis. Pickerel weed {Pontederia cordata) at its best, showing how well this commonnative looks in cultivation. Flowers pale blue. Needs checking occasionally
