Asparagus with Morels and Tarragon

'1 pound white asparagus, trimmed, peeled, and cut into 2-inch pieces', '1 pound green asparagus, trimmed and cut into 2-inch pieces', '3/4 stick (6 tablespoons) unsalted butter, cut into tablespoon pieces', '1/2 cup finely chopped shallots (2 large)', '1/4 pound fresh morels, cleaned and halved lengthwise if large', '1 tablespoon chopped fresh tarragon', '1/2 teaspoon salt', '1/4 teaspoon black pepper', '1 tablespoon fresh lemon juice', 'Garnish: chopped fresh tarragon'

Cook white and green asparagus separately in a 5- to 6-quart pot of boiling salted water , uncovered, until just tender, about 5 minutes for white asparagus; about 3 minutes for green asparagus. Transfer asparagus with a slotted spoon to a colander and rinse under cold water (to stop cooking), then drain again. Pat dry. Heat 3 tablespoons butter in a 12-inch heavy skillet over moderately high heat until foam subsides, then sauté shallots, stirring, until golden brown, about 2 minutes. Add morels and sauté, stirring frequently, until tender, about 5 minutes. Add asparagus, tarragon, salt, pepper, and remaining 3 tablespoons butter and sauté, stirring, until heated through, about 3 minutes. Remove from heat and stir in lemon juice. Serve immediately.
